The Harbor Inn in Pokemon Diamond is only accessible by using the Member Card. This item is only obtainable through an official Nintendo event.
practice on spelling for darkai diamond
To get inside the Harbor Inn on Pokemon Platinum you need the Member Card key event item. It is currently not possible to obtain the Member Card as the distribution events are no longer being held. The only way to get the Member Card is via a cheat device. The Harbor Inn has a NPC that can take you to the Island that houses the Pokemon Darkrai.
At the harbor inn at canalave city. You need a member pass which you can only get through a Nintendo event

i duno but try sometime when it gets dark, because you meet darkrai inside in a dream so it must have to be dark because darkrai is a dark type pokemon.

Action replay
you have to cheat
You could have only gotten a Mystery Gift through Nintendo in order to access the Harbor Inn in Canalave City in Pokémon Diamond however the key that's needed in order to gain access to the Harbor Inn, the Member's Card, it was never released for Pokémon Diamond so the only way for you to get the Member's Card is to use a cheating device such as an Action Replay or Pokésav.
In Canalave City above the Pokemon center
